ATS ATE cr me WILLIAM J'. NOON, OF LYNN, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO SIIVIEON J ROUSSEAU, OF LYNN, MASSACHUSETTS.

COUNTER-GUARD To all whom it may concern:

Be it known that I, WILLIAM J. Noon, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Counter Guards, of which the following is a specification.

This invention relates to guards used in connection with heel-trimming machines, to protect the upper at the counter. of the shoe from being scratched or otherwise injured by the cutter.

The invention particularly relates to a manner and means of mounting the guard so that it may move away from the cutter when the higher or thicker part of the heel is turned toward the same, and will be guided in so moving in a path which conforms to the final curvature of the heel edge, which is the same as the curvature of the cutting edges of the cutter blades.

It is accordingly the object of my invention to enable a shield for guarding the counter of a shoe to be mounted in such a way that it may move outward longitudinally toward and beyond the end of the cutter from its innermost position, wherein it somewhat overlaps the cutter, and in so moving, will be guided in the desired path.

Another object is to enable the path in which the shield moves to be varied correspondingly to dilferent styles of heels, so that the same device, except for a change in the guiding member, may be used in the trimming of shoe heels of a variety of styles.

In carrying out my invention so as to attain the objects stated, I have devised an attachment for heel-trimming machines, carrying a holder to which is secured a shield, with supporting devices for the holder permitting it to move both longitudinally and transversely of the axis of the cutter, and with a guide against which the shield holder is caused to bear, and by which the path wherein it moves is determined.

The preferred embodiment of the invention is illustrated in the accompanying drawing drawings, in which,

Figure 1 represents a plan view of the device in the relation which it occupies to the cutter of a-heel-trimming machine, Fig. 2

represents an elevation of a part of the device, as seen from the right of Fig. 1.

The same reference characters indicate the same parts in both figures.

Referring to the drawings, 1 represents the rotary cutter of a heel-trimming machine, and 2 the bearing in which its shaft rotates. This may be the cutter of any of the types of heel-trimming machine which are well known and now in use, and the attachment forming the subject of this inven tion is adapted to be mounted upon any one of such machines. The attachment consists of a bracket 3 which is detachably securable to a trimming machine in such a position 'that the guard or shield to be presently described, will be located in its proper relation to the cutter. This bracket contains a guideway in which is mounted a slide 4: carrying the members which support the counterguard. This slide is adjustable in the guide way and is held between two undercut gibs, one of which is adjustable so as to clamp the slide in any position, the adjusting means consisting of a bolt 7 passing through ears on the gibs and a clamp 8 screwed on the end of the bolt, which may be turned so as to bear against the adjacent gib and draw the head of the bolt against the other gib. An adjustable screw 9 in a rib 10 of the bracket 3 limits the motion of the slide inward.

On an arm or plate 11 forming a part of the slide 4 are pivoted two swivels or lugs 12 13, one being on each side of the plate and mounted on the same pivot-pin 14. These swivels are provided with lugs or sleeves 15 through which pass rods or arms 16, there being one carried by each of the swivels. These rods are capable of moving longitudinally in the lugs and together with the swivels, form pivotally-mounted arms to the outer ends of which is connected by means of pivot screws 17, the guard-holder 18 which carries the counter-guard shield 19. This shield is a curved plate which is adapted to lie near the periphery of the trimming cutter and partly embrace the same, its outer edge being flared outwardly and adapted to enter the groove between the counter and sole of a shoe at the heel seat.

The holder 18 is formed with integral extensions 20 at the opposite sides, which extensions merge into one another and are provided with lugs 21 between which is pivoted the end of a link 22. The other end of this link is pivoted to a stud 23 which is contained and guided in a plate 24 in the bracket plate 11. An adjusting screw 25 provided with a wing-nut 26 is passed through the plate 1.1 longitudinally of the slot, and prevented from moving longitudinally by the wing-nut 26 and a nut 27 threaded on its opposite end. This screw is threaded through the stud 28 and when rotated, serves to move the stud in the slot, and thereby projecting the link 22 and extension 20 more or less from the edge of the plate 11. The other end of the holder 18 carries a roll 28 which is adapted to bear against the outer surface of a block or plate 29 which I call for convenience a templet, that serves as a guide for determining the path in which the countershield 19 shall move. The roll 28 is held against the templet by the action of springs 30 surrounding the rod 16 and pressing between one of the sleeves 15 and an adjustable abutment 31. The roll 28 is adjustable with reference to the holder 18, being mounted in a head 32 having a threaded stem 33 which passes through the side of the holder and through a strap 34 secured thereto. Between the body of the holder and the strap is an adjusting nut 35 threaded upon the stem 33. The latter has a longitudinal groove (not shown) into which a project-ion of the holder extends, so that the stem cannot turn. Thereby rotation of the stem 33 serves to move the roll 28 nearer to or farther from the holder. It is secured in any position by a lock-nut 36 threaded upon the stem, which is clamped against the outer side of strap 34. By adjusting the position of the roll 28, and of the pivot stud 23, the holder 18 may be located at difierent distances from the body of the slide by which it is carried, and thereby the shield 19 may be adjusted to lie at any desired distance from the cutting edges of cutters of various sizes and shapes.

The shield is adapted to move longitudinally of the cutter by reason of the pivotal connection of the shield holder 18 to the arms 16 and 22. shown in F 1, by springs 37 of which one is attached to each of the rods 16 and adjustably connected with the supporting plate 11 by an eye-bolt 38 passing through a stud 39 on the plate 11, and carrying an adjustable nut 40 on the opposite side of the nut from the spring. The tension of this spring tends to swing the pivoted arms 16 to the right, and to carry and hold the link 22 against a stop 41 which is adjustable, and

It is held in the positionconsists of a set-screw threaded through a lug 411 on the plate 11. Another means for thus moving and retaining the holder 18 and shield 19 is found in the springs 42 coiled around the hubs of the swivel yokes 12 13, there being one spring for each yoke, one end of the spring being fastened to the yoke and the other to a stud 44 mounted upon the plate 11. The springs 37 and 42 perform the same function and may be used together, or either may be used alone, the other being eliminated.

Up-and-down movement of the holder is prevented both by the rods 16 and stationary supports or rests 45 46 which extend outward from posts 47 48 and embrace between them the extensions 20 of the holder. The outer ends of these rests 45 are provided with tubular rollers 49 which diminish the friction between the extensions and rests.

The shield is used in the usual manner in the operation of trimming a shoe heel. The shoe is placed with its tread against the flange of the cutter and the edge of the shield 19 is inserted in the heel-seat groove. As the shoe is turned during the operation of trimming the heel and the rear or thicker part of the heel comes adjacent the shield, the latter is moved away from the cutter in a longitudinal direction, and is constrained by the tension of the springs 30 and the re action of the templet 29 to travel in the path determined by the surface of the templet on which the roll 28 bears. This path is made to correspond with the edge outline of the cutter blades, and is consequently that of the heel when finished.

Movement of the shield in a path suitable for heels of other shapes is provided for by making the templet removable. To this end the templet is formed as a block having a stem 50 which is set into a hole 51 in the edge of the plate 11, and is secured by a thumb-screw 52. The templet may be withdrawn and replaced by another having a different outline on its bearing face.
